聚光型太阳能光伏光热系统（CPV/T）在传统光伏发电系统的基础上增加了聚光系统和光热系统，在通过聚光系统提高光伏效率的同时将系统中多余的热量加以利用，以达到太阳能最大化利用的目的。本文介绍了CPV/T系统的工作原理及其能效影响因素，以直接影响系统太阳能综合利用效率的聚光器技术、光伏电池技术和光伏冷却技术作为分析对象，结合近几年国内外最新研究成果比较了不同类型聚光器、光伏电池以及冷却方式的优劣，列举了常见的光伏余热利用方式。分析认为：CPV/T系统虽然具有更高的太阳能利用率，但应加大对系统尤其是聚光器经济性的分析；考虑在系统中应用叠层光伏电池缓解聚光器带来的系统体积过大问题；新电池开发过程中应更注意光伏电池的温度系数以减少冷却系统的压力，冷却技术在强化散热的同时也应注意热量的收集方法及其与利用途径的有效结合。
